To transfer solids with a weighing paper into a conical vial, you can follow these steps:
-
Place the weighing paper on the balance and tare it to zero.
-
Using a spatula or scoop, carefully transfer the solid sample onto the center of the weighing paper.
-
Lift the corners of the weighing paper and bring them together at the top, forming a cone shape around the sample.
-
Slide the overlapping edges of the weighing paper further together to create a smaller opening at the bottom of the cone.
-
With the tip of the cone facing downwards, gently insert it into the conical vial, making sure not to spill any of the sample.
-
Once the tip of the weighing paper is inside the vial, gently tap the weighing paper to release the sample.
-
Use a spatula or other tool to remove any remaining sample from the weighing paper and transfer it into the vial.
-
Repeat as necessary until all the desired sample has been transferred.
-
Once the sample is transferred, close the vial with the appropriate cap or closure and label it with the necessary information.
